^g-ithaliscus concinnus Gould, 1855. 



Our little Indian Tits hitherto known as erythrocephalus are 

 only a geographical race of the Chinese concinnus, moreover the 

 name itself cannot be used for this Tit as it is invalidated by 

 Linne's Pams erytJirocepJialus, x. ed. p. 191 (1758), and I have 

 tlierefore had to give it a new subspecific name.
